The last possibility on a CASE statement must be immediately followed by a colon.

Bad code

```al
CASE DimOption OF
    DimOption::"Global Dimension 1" :
        DimValue."Dimension Code" := GLSetup."Global Dimension 1 Code";
```

Good code

```al
CASE DimOption OF
    DimOption::"Global Dimension 1":
        DimValue."Dimension Code" := GLSetup."Global Dimension 1 Code";
```
